Abstract: A method of handling incoming calls directed to a virtual communication subscriber is disclosed. An incoming call intended for the virtual communication subscriber is received at a communication device. A call is placed to the communication device using contact information provided by the virtual communication subscriber. Extension information is provided to a SLS when the call is answered which corresponds to a communication line associated with the communication device. Upon connection to the communication device, the incoming call is bridged with the call placed to the communication device.

Abstract: A network interface unit is provided for use intermediate a LAN and a public or private network, or a combination of both, for establishing secure links to a VPN gateway. Login by a LAN client with the network interface unit, addressing, authentication, and other configuration operations achieved using a web page-based GUI are applied in establishing tunnels from LAN clients to desired VPN destinations. Illustrative network interface units include a DHCP server and provide encryption-decryption and encapsulation-decapsulation of data packets for communication with VPN nodes. Configuration and connection of a client are further enhanced by a built-in DNS server and other functional servers to provide a high degree of autonomy in establishing connections to a desired VPN gateway via an ISP or other public and/or private network links to. The interface unit then performs required authentication exchanges, and required encryption key exchanges.

Abstract: Paging, cellular telephone or other messaging functionality is incorporated into a virtual contact center system to permit logged-off customer service representatives (CSRs) to be alerted to a need to logon to the system, and to permit CSRs to alert supervisors or specialists to logon to the system. Matching at a contact control server of existing conditions to predetermined criteria, e.g., failure to login at an assigned time, or specified network conditions (such as length of customer queues), triggers a command for a communication to one or more logged-off CSRS. Results of follow-up testing at the contact control server for matches causes page requests to be renewed, redirected or canceled.

Abstract: Industrial pollution is directed into an afterburner conduit. An air cooled conical bluff body positioned in the conduit near the entrance acts as a flow condensing element. A recirculation zone consists of a toroidal vortex adjacent the downstream edge of the bluff body. In the zone, flow is reversed and particles in the reversed flow are reintroduced into the afterburner flow. A ring of burners located near the midpoint of the bluff body heats the gas stream flowing past the bluff body to near auto-ignition temperature. A second ring of burners located downstream of the bluff body assists in the establishment of a stabilized flame downstream of the bluff body. Air is heated as it flows through tubes wrapped around the conduit. The heated air is introduced tangentially to the afterburner flow by air injectors positioned downstream of the bluff body and downstream of the second ring of burners.

Abstract: Scrap automobiles are loaded onto carts which move along rails into a two-stage incinerator. Combustible waste is shredded, dried, and loaded onto a transporter which moves along the rails into the incinerator. The automobiles and combustibles are incinerated and the heat produced is collected. The heat is converted into steam used to power a turbine driven electricity generator. The generated electricity is used to electrolyze water and to operate an electric arc furnace which refines the incinerated metal. Heat from the incinerator is further used to heat waste oil in a cracking tower and to heat fermented organic waste in an alcohol still. The combustion gases are passed through a scrubbing tower where they are cooled and scrubbed with a caustic spray to neutralize acids present and they are passed through a bag house filter to remove particulate matter before they are vented into the atmosphere.

Abstract: A smoke control device for use in motor vehicle incineration. Smoke from burning vehicles in an incineration area is directed into a collecting chamber by controlled air flows and flaps. Updrafts evacuate the chamber and force the smoke into a combustion stack. The column of smoke in the stack is raised to combustion temperature by heaters mounted on the stack. The superheated smoke is combined with heated air in the vicinity of an open flame causing combustion resulting in a clear stack discharge.
